Low-complexity routing algorithm for smart metering on PLC

A routing algorithm is proposed to increase link reliability in smart metering over low-tension power line grid. The algorithm assumes data concentrator (DC) is polling meters connected to the power line to send energy consumption, loading profile and any other crucial data to the utility. The proposed algorithm is designed to keep the needed complexity at the meters at minimum, while moving the intelligence up to the DC. The protocol accounts for asymmetric characteristics of the power line channel, where some nodes couldn´t receive data from DC and neighbor nodes (deaf nodes), while its transmission could be received properly. Special packet structure is proposed to minimize algorithm overhead. Performance comparison with AODV protocol in terms of average throughput, reachability, and protocol overhead is in progress.
